The Integration of Planetary Science Simulation and Virtual Reality Geographic Information System

Abstract

A method for constructing a measurable virtual reality environment based on the ground image of the planetary exploration patrol device and the high-resolution satellite image is proposed. According to the three-dimensional images acquired by the patrol at different azimuth angles and height angles, a 360° panoramic image is generated through cylindrical projection, automatic matching and seamless stitching. At the same time, the inverse calculation function from the panoramic image to the original image has been developed, allowing users to directly measure on the panoramic image, and obtain 3D terrain information from the original stereo pair. The three-dimensional measurable panoramic image is seamlessly integrated with the planet browser based on NASA's World Wind, which provides a measurable virtual reality environment for planetary exploration applications, and realizes the integration from the vertical view satellite image to the ground horizontal view patroller imagemeasurement. At the same time, combined with the current popular computer research fields of virtual reality and three-dimensional technology, it focuses on the application of virtual reality and three-dimensional visualization simulation technology in geographic information systems, and analyzes virtual dynamic simulation, three-dimensional space analysis, virtual geographic environment, and three-dimensional data acquisition. Basic issues such as processing, three-dimensional data structure and models, and discuss the development trend of VR-GIS and 3D-GIS.
